Chewy Brownie Cookies

My mommy's group had a cookie bake-off for the holidays last Christmas then exchanged recipes. I thought these cookies were really really yummy and needed to input it (finally--6 mos later) before I lost the recipe! Hope you enjoy.

I substitute toffee chips for the nuts in these and whenever I give them to someone new I get begged for the recipe. SO GOOD. I think the people who had issue with the batter being runny might have used the wrong sized mix. The ones that are around 19oz are usually labled 'Family Size' or '9x13'. Everytime I've made these it's been so thick I had to use my heavy-duty wooden spoon to stir.
